yes. you'd most likely have to format your hard drive first and do a fresh install of an OS. if you did windows xp, there will be an option to choose which partition to install it on. if you want 2 partitions, select create and specify the size for each and then choose the one you want to install the OS on. If you don't want to wipe your hard drive, you could buy some program like PartitionMagic.
